Interaction of compost additives with phosphate solubilizing rhizobacteria improved maize production and soil biochemical properties under dryland agriculture

Alexandre Buttler, Luca Bragazza, Bjorn Jozef Maria Robroek, Muhammad Saleem Arif, Muhammad Riaz, Muhammad Ashraf

Dry land soils from the Indo-Gangetic plains are inherently poor in organic matter content and phosphorus (P). Amendment of these soils with P-enriched compost, together with P solubilizing rhizobacterial (PSR) inoculation has been suggested to improve pla ...

Simulating the influence of snow surface processes on soil moisture dynamics and streamflow generation in an alpine catchment

Michael Lehning, Nander Wever, Francesco Comola, Mathias Thierry Pierre Bavay

The assessment of flood risks in alpine, snow-covered catchments requires an understanding of the linkage between the snow cover, soil and discharge in the stream network. Here, we apply the comprehensive, distributed model Alpine3D to investigate the role ...

Linear scaling of precipitation-driven soil erosion in laboratory flumes

David Andrew Barry, Seifeddine Jomaa

The proportionality between raindrop-driven soil erosion delivery and area of soil exposed to raindrops under a uniform precipitation rate was investigated in terms of individual size classes using laboratory flume experiments. In particular, we examined t ...

Precipitation, soil moisture and runoff variability in a small river catchment (Ardeche, France) during HyMeX Special Observation Period 1

Jacopo Grazioli, Timothy Hugh Raupach

Flash flooding is a potentially destructive natural hazard known to occur in the Cevennes-Vivarais region in southern France. HyMeX (Hydrological Cycle in the Mediterranean Experiment) is an international program focused on understanding the hydrological c ...

Land use and soil texture effects on organic carbon change in dryland soils, Senegal

Claire Guenat, Assize Touré

Soil organic carbon (SOC) losses due to poor soil management in dryland are now well documented. However, the in- fluence of soil properties on organic carbon change is not well known. The groundnut plant (Arachis hypogaea L.), and the dominant crop system ...

Analysis of carbon and nitrogen dynamics in riparian soils: Model development

David Andrew Barry, Alessandro Brovelli, Jordi Batlle-Aguilar

The quality of riparian soils and their ability to buffer contaminant releases to aquifers and streams are connected intimately to moisture content and nutrient dynamics, in particular of carbon (C) and nitrogen (N). A multi-compartment model – named the R ...

Ecohydrological Footprints : Quantitative Response of Ecosystems to Changes in their Hydrological Drivers

Samir Suweis

Ecohydrological footprints are defined as the response of ecosystem functions or services to changes in their hydrologic drivers. In this thesis, several diverse footprints are addressed: noise-driven effects on storage-discharge relations and catchment st ...

Prescription-induced jump distributions in multiplicative Poisson processes

Andrea Rinaldo, Samir Suweis, Amos Maritan

Generalized Langevin equations (GLE) with multiplicative white Poisson noise pose the usual prescription dilemma leading to different evolution equations (master equations) for the probability distribution. Contrary to the case of multiplicative gaussian w ...

Combined estimation of effective electrical conductivity and permittivity for soil monitoring

Alessandro Brovelli

The mapping of moisture content, composition and texture of soils is attracting a growing interest, in particular with the goal of evaluating threats to soil quality, such as soil salinization. Fast non-invasive geophysical surveys are often used in this c ...

Stochastic modeling of soil salinity

Andrea Rinaldo, Samir Suweis, Amos Maritan

A minimalist stochastic model of primary soil salinity is proposed, in which the rate of soil salinization is determined by the balance between dry and wet salt deposition and the intermittent leaching events caused by rainfall events. The long term probab ...
